Contact Class

This class stores the result of a physical contact (coordinates of the point, contact duration, penetration depth, contact object, physical shapes participating in the contact, index of the contact surface). This class can be used for implementation of your own custom physics or a custom player.

Contact Class

Members


static Contact ( ) #

Contact class constructor.

void setId ( int id ) #

Sets a new contact ID.

Arguments

  • int id - Contact ID.

int getId ( ) #

Returns the contact ID.

Return value

Contact ID.

void setSurface ( int surface ) #

Sets a new contact surface number.

Arguments

  • int surface - Contact surface number.

int getSurface ( ) #

Returns the contact surface number.

Return value

Contact surface number.

void setTime ( float time ) #

Sets the time when the contact occurs. In case of CCD (for spheres or capsules), it's the time starting from the current physics simulation tick to the moment when the calculated contact is bound to happen. In case of non-continuous collision detection, it is always 0.

Arguments

  • float time - Contact time, in milliseconds.

float getTime ( ) #

Returns the time when the contact occurs. In case of CCD (for spheres or capsules), it returns the time starting from the current physics simulation tick to the moment when the calculated contact is bound to happen. In case of non-continuous collision detection, 0 is always returned.

Return value

Contact time, in milliseconds.

void setDepth ( float depth ) #

Sets a new penetration depth of the contact. This distance is measured along the contact normal.

Arguments

  • float depth - Contact depth, in units.

float getDepth ( ) #

Returns the penetration depth of the contact. This distance is measured along the contact normal.

Return value

Contact depth, in units.

void setPoint ( Vec3 point ) #

Sets new coordinates of the contact point.

Arguments

  • Vec3 point - Coordinates of the contact point, in world coordinate system.

Vec3 getPoint ( ) #

Returns the coordinates of the contact point.

Return value

Coordinates of the contact point, in world coordinate system.

void setNormal ( vec3 normal ) #

Sets new normal coordinates at the contact point.

Arguments

  • vec3 normal - Normal coordinates at the contact point.

vec3 getNormal ( ) #

Returns the normal coordinates at the contact point.

Return value

Normal coordinates at the contact point.

void setShape0 ( Shape shape0 ) #

Sets the first shape participating in the contact.

Arguments

  • Shape shape0 - First shape participating in the contact.

Shape getShape0 ( ) #

Returns the first shape participating in the contact.

Return value

First shape participating in the contact.

void setShape1 ( Shape shape1 ) #

Sets the second shape participating in the contact.

Arguments

  • Shape shape1 - Second shape participating in the contact.

Shape getShape1 ( ) #

Returns the second shape participating in the contact.

Return value

Second shape participating in the contact.

void setObject ( Object val ) #

Sets the object participating in the contact.

Arguments

  • Object val - Contact object.

Object getObject ( ) #

Returns the object participating in the contact.

Return value

Contact object.
